Intuit has integrated QuickBooks Point of Sale with GoPayment
free credit card mobile payment app. This is in direct competition to Square,
and it's iPad register.

Finally the 200,000 customers who use QuickBooks POS
hardware and software have an easy way to combine a traditional POS
experience with a mobile payment service. Plus, new business owners who need a
remote selling option and want to use QuickBooks software will be jumping onto
the POS bandwagon.

QuickBooks POS starts at $1,499 for the pro version, the minimum version
worth buying. With hardware, the pro version costs $1,899. The pro multi-store
software sells for $1,799 and $2,299 with hardware. Square will obviously
continue to do very well, but it doesn't integrate with QuickBooks yet. Plus, Intuit
has an advantage with POS being a more robust solution for bigger merchants
with more transactions.

First you setup QuickBooks software, and get that working. Then you setup
POS and mark each inventory item you want to sync to the GoPayment iPhone app. You
use your iPhone to take payments anywhere you're not connected to a cash
register, or computer, such as trade shows or events. At day's end, you sync the
sales back to POS for accurate inventory counts, and then sync the financial data
back into QuickBooks software for sales receipts & deposits. Your sales
receipts determine sales tax liability, and income figures on the P&L
Report. Overall, Intuit has provided an excellent solution to managing
inventory and financials.

If you need help setting up any of this, please contact me. I'd love to
help you!
